This Powerpoint Presentation is Part II/II of an Ecology: Trophic Feeding Levels Unit Powerpoint that can be downloaded at http://sciencepowerpoint.com/index.html
The 700+ slide unit Powerpoint, assessment, and class notes become the road map for an exciting and interactive unit full of lab activities, challenge questions, discussion opportunities, project ideas, assessments, modified assessment, review games, answer keys, videos, and much more.
The Ecology: Trophic Feeding Levels Unit covers ecology topics associated with the Concept: There Is No Such Things a Free Lunch. This unit explores how energy travels through an ecosystem and focuses on thermodynamics (See list below for more topics covered). . Text is in large print (32 font) and is placed at the top of each slide so it can seen and read from all angles of a classroom. A shade technique and color coding of text helps increase student focus and allows teacher to control the pace of the lesson. Important vocabulary words are addressed throughout the unit . Also included is a 7 page (Microsoft 2003 word doc.) assessment / bundled homework that chronologically follows the slideshow for nightly homework and the end of the unit assessment, as well as a 5 page modified assessment. 5 pages of class notes (Word doc.) with images are also included for students who require modifications, as well as answer keys to both of the assessments for support professionals, teachers, and homeschool parents. 7 video shorts (FLV files) are provided and a slide within the slideshow cues teacher / parent when the videos are most relevant to play. Video shorts usually range from 2-7 minutes and are included in organized folders. One Powerpoint review game is included. Answers to the Powerpoint review game are provided in Powerpoint form so students can self-assess. Lastly, several class games such as guess the hidden picture beneath the boxes, and the find the hidden owl somewhere within the slideshow are provided. Difficulty rating of 4 (Ten is most difficult). All of the above is organized into folders and can be changed to fit your needs or time requirements.
Areas of Focus within the Ecology: Feeding Levels Unit: -What is Ecology, Concepts in Ecology, Concept-There is no such thing as a free lunch, Energy Comes From the Sun, Food Chains, Trophic Feeding Levels, Producers, Consumers, Decomposers, Aquatic Food Chains, Phytoplankton, Zooplankton, Bioaccumulation, Biomagnification, Animal Dentition, Carnivores, Herbivores, Pyramid of Biomass, Pyramid of Numbers
Please visit www.sciencepowerpoint.com to learn more about this unit, and the 19 other units in Life, Earth, and Physical Science for students in grades 5-10. Thank you for your time and interest. Please view part I and the review games on my shelf. Thank You.

• RED SLIDE: These are notes that are very important and should be recorded in your science journal. • BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly.

• Activity- Animal Dentition
– Roll modeling clay into a flat sheet. – I am going to pass around different animal skulls. – Make an impression of the teeth by using the clay. (Do not make a mess of the skull, that is, be scientific, precise and methodical. – Draw two teeth imprints in your journal and identify the tooth.

• Activity – Biomass Pyramid
– Separate the producers (roots as well), consumers, second order consumers, and decomposers into different trays. – Place each trophic level in a Petri-dish and weigh the samples. – Count the number of individuals in each Petri-dish (trophic levels) to create a pyramid of numbers. – Include neatly drawn pyramids in your journal.

• If we were trapped on a fertile grass Island, about the size of a soccer field, should we plant food crops or graze animals.
– Island can produce 10,000 different edible plants. – Island can provide food to graze one small cow, and two goats. They can produce a few glasses of milk daily.

• Answer – We should plant crops. There is more available energy in producing vegetables than animals.
– We may get 10,000 plants. – The field may support one small cow which will just give a small amount of milk, even less energy if we use our one animal for BBQ.

• Follow up Questions.
– Please color each glass as accurately as possible to show the relative concentrations of food coloring. – The food coloring represents available energy. – Which feeding level had the most, least, and in the middle, of available energy? – Why did the decomposers get energy from all on the containers?

• Follow up Questions.
– Which feeding level had the most, least, and in the middle, of available energy? – Answer: The test tube labeled the producers which was the darkest blue had the most available energy. 3rd Order Consumers contained the least available energy.
